兰州市2001年沙尘气溶胶质量浓度的特征分析

摘要/Abstract

摘要： 分析了2001年沙尘暴期间兰州与靠近沙尘源区的武威的沙尘浓度和粒径分布特征,并运用对数正态分布规律拟合了沙尘粒径的分布。通过对比武威、皋兰和兰州沙尘暴期间沙尘浓度的变化以及武威与兰州的沙尘粒径分布特征,揭示了河西走廊沙漠对兰州市沙尘暴的影响。

Abstract: The aerosol concentration and particle-size distribution during sand-dust storm processes during 2001 in Lanzhou city at leeward and Wuwei city at windward are analyzed in this paper. A log-normal model is used to stimulate the particle size distribution of aerosols. Through comparing the day-to-day change of aerosol concentration and the particle size distribution in Wuwei and Lanzhou, we get that desert in Hexi corridor of Gansu province has great influence on the aerosol concentration and particle-size distribution of Lanzhou city.

Key words: dust storm, mass-particle size distributions, PM10, source of dust
